Mouse cursor disappearing on second monitor
I am using a Macbook Pro (16-inch, 2021) with a DELL U2415 Display monitor. The cursor remains visible on the laptop screen, but constantly disappears / flashes on the monitor. I have seen the suggestion to got to System Preferences > Accessibility > Display and increasing the cursor size there, but this does not work for more than a couple of seconds. Do you have any other suggestions? Many thanks.
